Title: Method for detecting electrical angle at start of variable reluctance motor
Inventor: SAKANO TETSURO
IPC: H02P6/08
Filed: 1992-12-02
Abstract: PURPOSE:To detect the electrical angle at start without using an absolute type rotary encoder or rotating a motor by measuring two or more phases of inductance at excitation of an exciting coil, and determining the electrical angle of a rotor by the inductance. CONSTITUTION:For a variable reactance motor, the gap between the rotor and the salient pole teeth of a stator is small, so the inductance at excitation of each phase of exciting coil changes in proportion to the areas of opposed both pole teeth. The inductances La and Lb are measured from the rates of changes of current values by causing minute current to flow to two or more phases. The electrical angles Qa1, Qb1, and Qb2 corresponding to the detected inductances are determined. The common electrical angle is made the electrical angle at start. Hereby, the electrical angle at start of a variable reluctance motor can be determined without using an expensive absolute type rotary encoder.
